Abstract (en)

An interface circuit comprises a first integrated circuit (200) to transmit or receive data, a second integrated circuit (300) connected to the first integrated circuit by a transmission line (TL) to transmit or receive data, and a constant current generating circuit (100) connected to the transmission line so as to output a current of a constant magnitude (I2) to the transmission line. The constant current generating circuit (100) adjusts the amount of current (I2) outputted to the transmission line by sensing a voltage level (N1) of the transmission line.
